Track inventory in QuickBooks

If your company sells products to customers, you may want to track inventory.
QuickBooks can track inventory levels, decrease inventory quantity automatically
when you make a sale, and prompt you to reorder inventory when your levels are
low.

I have more questions

There are several inventory management software applications
available. Some of them are designed to integrate with QuickBooks
so that you manage inventory within the third-party application, but are able to
view inventory information within QuickBooks.

Many third-party software applications have the ability to export journal
entries into a format that can be used by QuickBooks. If you use third-party
inventory software, work with the software vendor or a professional advisor to
help you export data from the inventory software and import it as journal
entries into QuickBooks.

It is important to set up and map the fields from the inventory software
to the fields in QuickBooks. Before doing any imports, back
up all of your QuickBooks data correctly. After you import information,
review your chart of accounts, your items list, and your financial reports
to ensure the entries imported correctly.

If your third-party inventory application does not integrate with QuickBooks,
you may still be able to use some data in QuickBooks. Some examples
of this include:

A fruit juice company purchases its raw goods—prunes—for use in its prune juice.
After the prunes have been pitted they are ground and combined with water to become the finished product—prune juice.
What was originally measured by weight (the prunes) are now measured by volume (the prune juice). Their juice-industry specific software manages all the costs to
determine the cost of goods sold for each case of juice.

In QuickBooks, the company tracks the raw goods as an asset, but they do not
add items to inventory until the third-party inventory application determines the
cost of goods sold for each unit.

Another company purchases the raw goods to make pizza (flour, tomato sauce,
cheese, etc.) with QuickBooks. They "sell" the goods to another
inventory application that manages the ingredients used to create a pizza.
QuickBooks then "buys" the pizza as an inventory item from the
third-party inventory application and sells it as it would any other inventory
item.
